Nonstop flight route between Washington, D.C. / Virginia, United States and Dillon, Montana, United States:

About this route:

A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Dillon Airport (DLN), Dillon, Montana, United States would travel a Great Circle distance of 1,836 miles (or 2,954 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the relatively short distance between Washington Dulles International Airport and Dillon Airport, the route shown on this map most likely still appears to be a straight line.

• Because of Washington Dulles International Airport's relatively low elevation of 313 feet, planes can take off or land at Washington Dulles International Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
• At the end of World War II, growth in aviation and in the Washington metropolitan area led Congress to pass the Washington Airport Act of 1950, providing federal backing for a second airport.
• Washington Dulles International Airport (IAD) has 5 runways.
• The furthest airport from Washington Dulles International Airport (IAD) is Margaret River Airport (MGV), which is located 11,659 miles (18,763 kilometers) away in Margaret River, Western Australia, Australia.
• The C and D concourses, completed in 1983 and designed by Hellmuth, Obata and Kassabaum, were originally designed as a temporary base for United Airlines, which began hub operations at the airport in 1985.
